Short description Morfologia | Morfometria

Spine dorsali (totale): 10 - 12; Raggi dorsali molli (totale): 11-13; Spine anali 3; Raggi anali molli: 8 - 10. Bluish grey above, paler below with a silvery sheen; fins blackish brown (Ref. 6633). Juveniles have black blotches on head and body (Ref. 6633). Body tall, compressed. Big mouth with big head and a rough bony ridge across upper part of the gill cover (Ref. 35388).

Biologia     Glossario (es. epibenthic)

Adults prefer to inhabit caves and shipwrecks (Ref. 27121). Juveniles congregate below floating objects (Ref. 27121). Usually solitary. Feed on large crustaceans, cephalopods and benthic fishes (Ref. 27121). Spawn in the summer (Ref. 35388). Are primary gonochorists (Ref. 58421). Marketed fresh or frozen; eaten steamed, fried, broiled, boiled, microwaved and baked (Ref. 9988). Minimum depth reported from Ref. 6633.
